Joule Thief

[sparks]

  Here is a great application for a Jule Thief.  Your battery is dead in your auto.  You hit the I shouldnt of left the headlights on switch.  The julethief charges up an auxiillary bank of series connected supercaps from your dead battery.  Initial current surge to your starter motor is what does the trick.  After the initial surge the resistance of the copper chokes off the current due to conductor heating.  Unless the motor is revolving and some counter rotating magnetic field generation to drop off the current levels needed from the battery its a case of diminishing returns and out comes the triple a card.

I have taken a look at your video and I go with Bill on this, storing the DC charge is the issue here. What is the current draw to run your motor with your present set up? You  need 1000 volts!! so you need some hefty caps that have to be both charged  and be capable of  delivering their charge within your time frame. We need to know what current demand is required at your target voltage to get an idea of what can be the best approach.

I really appreciate the help.  First, the schematic below was suggested to me by Jadaro2600, and I think this is what you are suggesting I need.

The second schematic show how I now have it.  Just a slight difference.  For the Cap on the right, I have tried several sizes -- 68uF, 330uF. 

Joseph Newman's theory:  The magnetic field in a inductor/coil, is the result of aligning the atoms in the wire.  Voltage is the force that is aligning the atoms, not current.  There are three ways of generating larger magnetic fields.  Add more voltage, or add more atoms/wire, or both.

Joseph Newman's first motor consisted of over 4000lbs of copper wire.  With this much copper wire, only 1 1/2 watts of power (I think he said there was about 60+ volts), was needed to turn a 600lb magnet!!!!

I am on my third build.  The first one has been disassembled, to use the wire on motor #3.  I have been using some of the wire from build #2 to make Joule Thiefs, and recently rebuilt #2 to show a friend, but I don't plan on keeping it.  Currently, the coils on #3 have a total DC resistance of 1155ohms.  Each pound of 30awg wire is about 700ohms.  What I am trying to prove with my motor, is whether or not Newman is correct about only needing voltage.  So a high voltage should get motor #3 really spinning.  I will accept any help to get 500v or more.  Once I start adding more wire, I should be fine with less than 1000v.  But I do want to know how to get 1000+ out of any of the transformers I have.

Again Thanks for all the help.

Detrex:

Some of us have run Bedini motors from our JT's.  I have read about Newman motors but do not really understand how they are supposed to work.

It may be possible to dump the ac spikes from the JT into a very large Farad cap (I have used two 10 farad caps and later a 650 farad cap for this purpose) which will convert (or appear to convert) the spikes into usable power for your motor.  Now if you need to rectify it before the cap or not, I do not really know.  I didn't have to with the Bedini but, as I said, I am not sure what your motor really needs.

@Pirate:  How long does it take to charge up the 650 farad cap?  or the 10 farad cap?  And how much does a 10 farad 500v supercap cost?

Hello everyone ..
new design of my lamp JT (lamp stands for point lights), in fact, he shines so much better when there is no substitute for light paraffin candle at 200%.
This can give or sell !

Nicely done.
